1307.4378 (Rui Wang et al.)

J/ψ,Υ(1S) and χb(3p) Production Measurement with the
ATLAS Detector

Rui Wang, On behalf of the ATLAS Collaboration
The J/{\psi} and {\Upsilon}(1S) production cross-sections are measured in proton-proton collisions using the ATLAS detector at the LHC. Differential cross-sections are measured as a function of transverse momentum and rapidity. Results are compared to QCD predictions. A new {\chi}b state has been observed though radiative transitions to the {\Upsilon}(1S) and {\Upsilon}(2S) states.
